People had crowded onto the bridge over the River Bure to see a clown go down the river in a barrel; their weight shifted as the barrel passed underneath, the suspension chains snapped and the bridge deck tipped over.

Bridge completely destroyed, no person killed, but one dog killed and three vehicles lost.

Became known as "Galloping Gertie", in the first 4 months after opening up until its collapse under aeroelastic flutter. Since that time most major new bridges have been modelled in wind tunnels. Rebuilt in 1950; parallel span opened in 2007.

Capture of intact bridge offered significant short term tactical advantage to Allied forces. Collapse was not strategically significant due to placement of parallel floating bridges during the previous week

Collapsed during construction due to poor design and ill-advised construction methods

35 killed

112-metre (367 ft) span between piers 10 and 11 collapsed

Cantilevered section under construction sprang back and collapsed following attempts to remove a buckle caused by a difference in camber of 11 cm (4.5 inches) between it and the other section of the span to which it was to be joined

Ore freighter Lake Illawarra collided with pylons. A 400-foot (120 m) section of bridge collapsed onto freighter and into the river. Four cars drove off bridge

12 killed (7 ship crewman and 5 motorists)

2 pylons and three sections of bridge collapsed, ore freighter sank, 4 cars fell into river

City of Hobart was split in two. Residents living in the east were forced to make a 50 kilometres (31 mi) trip to the CBD via the next bridge to the north. Missing sections were reconstructed and the bridge reopened on 8 October 1977

The bridge was supported by two piers situated between the various rail tracks. Part of the derailed train virtually demolished the northern pier, resulting in the collapse of the northernmost span of the bridge.

The Mill Point Bridge is 3 miles (4.8 km) upstream from the Thruway bridge that collapsed on 5 April. Flood waters from the same flood that finally undermined the Thruway bridge were up to the girders of the Mill Point bridge. It was closed as a safety precaution. It collapsed six days after the earlier collapse.[20]

As a result of rising flood waters and ice floe from the North American blizzard of 1996, when high floodwaters and a large ice floe lifted the spans off their foundations and swept them down the river.

Lost two of its seven western spans, A third span was damaged and later collapsed into the river.

Western span of the Walnut Street Bridge after it collapsed during the 1996 flood. The eastern span is still in use for pedestrian traffic.

Northbound right lane began to buckle during the morning rush hour and sagged a few feet below normal. Damage was said to have been caused by extremely cold weather, snow, and heavy amounts of traffic.

The collapse had a significant economic impact on the region since the Causeway is the only road connecting South Padre Island to Port Isabel. The bridge also carried electricity lines and fresh water to the island. State officials brought in ferries to temporarily carry cars across the Laguna Madre. Repair cost for the bridge was estimated US$5 million.

Partial failure under load of transport truck during severely cold temperatures. Fatigue fractures of three steel hanger rods cited to be primary reason for failure.

Partial failure of bridge deck. Overhead superstructure undamaged.

Bridge reopened after complete reconstruction. Existing overhead arch remained, however new bridge deck was designed to be supported by sets of 4 hanger cables, where the existing deck was designed for single hanger cables.

As part of a construction project, a girder twisted, sagged, and fell onto I-70. An SUV was driving eastbound and struck the fallen girder; the top of the vehicle was torn off and the three passengers died instantly.[28]

Currently under investigation,[needs update] believed to be linked to the fact that local contractors often opt for shoddy materials to cut costs and use migrant laborers with little or no safety training

34 killed, 22 injured

Total collapse

Collapsed during construction as workers were removing scaffolding from its facade

Collapse of a temporary pillar due to the sandy foundation it was set on.[42]

55 killed, hundreds injured

Section buckled while construction was underway

Pieces of Cần Thơ Bridge remaining after its collapse on 4 October 2007, ten days after the accident.

A preliminary investigation discovered that the engineers had underspecified the loading capacity of the scaffolding in several ways, but ultimately it was determined that the unevenly settling foundation was the primary cause of the collapse.

Truss bridges like this one require both the top and the bottom to remain equal in strength and solidity. When the truck hit the top girder, or girders, this caused the pressure/squeeze system to fail, which made the bridge fold up. The design was outdated; more modern types of truss can better withstand such forces.

A Union Pacific train T-boned a Burlington Northern Santa Fe train outside of Scott City, Missouri at approximately 2:30 am. The impact caused numerous rail cars to hit a support pillar of a highway overpass, collapsing two sections of the bridge onto the rail line. Two cars ended up driving onto the collapsed sections, injuring three people in one vehicle and two in the other. Two people on one of the trains were also injured.[65][66]

Bridge collapsed during concrete casting, with debris falling onto open motorway below and narrowly missing vehicles, closing major motorway E47 for several days. The remains of the bridge were subsequently demolished and a replacement built elsewhere.[67]

Bolts holding together a section of the bridge snapped,[71] due to design and construction errors.[72]

No injuries were reported

West side of bridge separated from abutment and rose 60 cm above grade, but not seriously damaging the span

Newly constructed bridge failed after only 42 days of use. Because the bridge failure severed the only road link within Canada between Eastern and Western Canada,[73] a temporary repair was completed the next day by adding weights to depress the span into position.[74]

Slings snapped while 70 people were on the bridge during Nyepi celebration in Bali. Authorities stated that the sling cables that snapped could have been caused by overloading. Most witnesses stated that before the collapse, the bridge had swayed and shook for several times.[79][80]
